Systems / Causal experiment lab
Reactive light machine
Discover how switches and previous states shape the next pattern of lights.
Discover how two switches and the previous three lights determine the next lights. Experiments reset the whole state; missions carry it forward.
Patterns are written C B A. Switch patterns are V U. All three lights update together. Reach each target in at most four steps.

Need a hint?
Try holding the switches fixed and changing the starting lights. The rules are: next A = U XOR old C; next B = old A OR V; next C = old A XOR old B.
